CY62256

CY62256 256K (32K x 8) Static RAM Features Functional Description [1] z Temperature Ranges The CY62256 is a high-performance CMOS static RAM -Commercial:0 to 70 organized as 32K words by 8 bits. Easy memory expansion is -Industrial: -40 to 85 provided by an active LOW output enable ( ) and active LOW -Automotive: -40 to 125 output enable ( ) and three-state drives. This device has an z High speed: 55ns and 70 ns automatic power-down feature, reducing the power consumption z Voltage range : 4.5V –5.5V operation z Low active power (70ns, LL version, Com’l and Ind’l) -275mW (max) z Low standby power (70ns,LL Version, Com’l and Ind’l) -28 µW (max.) by 99.9% when deselected. An active Low write enable signal ( ) controls the writing/reading operation of the memory. When and inputs are both LOW, data on the eight data input/output pins (I/O0 through I/O7) is written into the memory location addressed by the address present on the address pins (A0 through A14). ...
